The risk of long COVID reaches 37% after three infections, according to the INSPQ

As COVID-19 continues to circulate widely, a report from the INSPQ warns that the risk of getting long COVID increases with each reinfection, and notes that the Quebec health system is failing to help the growing number of people who have had persistent symptoms for months or even years.

The report by the Institut national de la santé publique du Québec (INSPQ), which surveyed thousands of health workers in Quebec who were infected between the beginning of the pandemic and summer 2023, was released quietly on Monday. Yet, this report warns that post COVID-19 condition, commonly known as long COVID, is affecting more and more people.

« This is an important and real issue. We want to raise awareness among the public and public health authorities,” says Sara Carazo, one of the authors of the report.

What Repeat COVID Infections Do to Your Body, According to Science

These days, it’s tempting to compare COVID-19 with the common cold or flu. It can similarly leave you with a nasty cough, fever, sore throat—the full works of respiratory symptoms. And it’s also become a part of the societal fabric, perhaps something you’ve resigned yourself to catching at least a few times in your life (even if you haven’t already). But let’s not forget: SARS-CoV-2 (the virus responsible for COVID) is still relatively new, and researchers are actively investigating the toll of reinfection on the body. While there are still a lot of unknowns, one thing seems to be increasingly true: Getting COVID again and again is a good deal riskier than repeat hits of its seasonal counterparts.

It turns out, SARS-CoV-2 is more nefarious than these other contagious bugs, and our immune response to it, often larger and longer-lasting. COVID has a better ability to camouflage itself in the body, “and it has the keys to the kingdom in the sense that it can unlock any cell and get in,” says Esther Melamed, PhD, an assistant professor in the department of neurology at Dell Medical School, University of Texas Austin, and the research director of the Post-COVID-19 program at UT Health Austin. That’s because SARS-CoV-2 binds to ACE2 receptors, which exist in cells all over your body, from your heart to your gut to your brain. (By contrast, cold and flu viruses replicate mostly in your respiratory tract.)

Why do we have to keep getting COVID?

Flannery Dean is a writer and editor based in Hamilton.

Nearly five years into life with COVID-19, I find myself selfishly wondering how many more times I – by which I mean, all of us – need to get it before we acknowledge that allowing multiple reinfections poses a very large problem? I thought my second bout of it (or was it my third?) in February, 2023, was tough – that one set me back a few months. But this nasty little bug, which is again surging here, there and everywhere, has bitten me once again, and has been a beast to overcome.

My latest infection – which began in June and is mild by medical standards – surprised me. I’m an active, healthy woman in her 40s. In addition to having been infected previously, I’ve gratefully received every single vaccine offered, including the booster shot only about 18 per cent of Canadians got last fall. I’m not sure I blame those who didn’t rush out in droves to get it. There was little public push to do so, and a general sense that infection after vaccination was okay so long as you’re “healthy.” Continued protection against a virus that makes swift and powerful adaptations is a hard sell when you don’t invest in the power of prevention, too.

Even so, after the fever passed, I spent a month largely confined to my bed, unable to do more than shuffle to my doctor’s office and back. I felt weak and nauseated in a way that made pregnancy queasiness seem quaint. My muscles felt tired or tingling or cold, or all three at once. I was regularly overcome by a sensation that I can only describe as a full-body panic attack, marked by a racing heart and rapid breathing. For weeks, I felt like my internal circuitry was on the fritz. Even my vision was blurred.

It remains so.

Is It Dangerous to Keep Getting COVID-19?

People who had multiple infections were three times more likely to be hospitalized for their infection up to six months later than those who only got COVID-19 once, and were also more likely to have problems with clotting, gastrointestinal disorders, kidney, and mental-health symptoms. The risks appeared to increase the more infections people experienced.

Does the risk of getting long Covid increase each time you get reinfected?

More than three years into the coronavirus pandemic, fewer and fewer people are experiencing their first Covid-19 infections. But as cases climb, those who’ve had the virus before may wonder: What are their chances of developing long Covid — and does the risk increase with each reinfection?

Some seniors infected with Omicron variants were more susceptible to reinfection, not less: McMaster study

In a sign that scientists still don’t fully understand how some COVID-19 variants manage to evade the immune system, a new Ontario study has found that retirement- and long-term-care home residents infected during the first Omicron wave were 20 times more likely to get reinfected by the virus than those who avoided a prior infection.

The surprising finding by researchers at McMaster University runs counter to the prevailing wisdom that a previous COVID infection affords protection against future infections, at least in the older adults who participated in the study.

Do Repeat COVID Infections Increase the Risk of Severe Disease or Long COVID?

Many repeat infections are mild, but some studies suggest people who have been infected with COVID more than once are at a greater risk of severe disease or long COVID.

We Now Face an Army of COVID Viruses

As leaders have shifted to the position that masks and tests are matter of personal choice rather than collective self-preservation, they have implicitly silenced a vital message to the citizenry about how pandemics actually come to an end. It is this: less transmission means fewer mutations; fewer mutations means less variation, the fuel of evolution. Reducing infections, then, puts the brakes on viral evolution.

The combined actions of “letting the virus rip” in a population with varying degrees of protective and waning immunity created by vaccines or previous infections “has led to unprecedented increase in viral diversification in 2022,” as one group of researchers explained in a recent paper published in the International Journal of Molecular Sciences.

Ten COVID Facts Health Officials Dangerously Downplay

Do not listen to powers that be who pretend that getting infected with COVID multiple times is now no big deal. They’re asking you to lower your guard for a nasty virus that can invade the brain, disregulate the immune system and damage the vascular system.

This strategy has led to predictable results — more direct deaths, more excess deaths, more disease and some 1.4 million Canadians reporting some form of long COVID over the last two years.
